We had the Hills swing set in our backyard. I think it was a Christmas present around 1969.However, the best swing of all was at my uncle's house. They lived in Montrose and had a flat roofed house. The tyre swing was on a high branch of a very tall gum. My uncle would supervise us all onto the roof, while he held the rope that trailed under the tyre. We would ease off over the gutter and then he would let go. Best. Swing. Ever.My mother hated his guts and his revenge was to have a lot of fun with us kids. I don't know who enjoyed it more - us or him - because it certainly used to get her cross. We never had an accident, but if we had; it would have been catastrophic. Ah, childhood. Ignorance, and being caught in the moment, is bliss. :)
